Copying an image from one server to another

[ioannes <ioannes@xxxxxxxxxxxxxx>]

I am trying to:

- check whether an image file exists on a server,
- check whether it does not exist on another server, and if not exists
- to copy from the first location to the second.

I am using cURL.  First step to capture the image from the first 
server.  When I return this image to the browser I get a lot of strange 
characters.  So has this captured the image and what do I use next to 
upload to the second server?

I was trying to use file_exists and had problems referencing the file 
location as "http://wwww.mysite.com/pic.jpg";.  But I know I can also 
look at using readfile() and file_put_contents(), $fp = fopen(), 
fputs(), fpassthru() etc.  What is best way?

       // create a new cURL resource
       $ch = curl_init();
       $url="http://wwww.mysite.com/pic.jpg";;
       curl_setopt($ch, CURLOPT_URL, $url);
       curl_setopt($ch, CURLOPT_HEADER, 0);
      
       // copy the handle
       $ch2 = curl_copy_handle($ch);
      
       // grab URL and pass it to the browser
       curl_exec($ch2);
      
       // close cURL resources, and free up system resources
       curl_close($ch2);
       curl_close($ch);
